My great-grandfather was Thomas Husson, who went to the US from England. He came from St Agnes in Cornwall, and his father was born in Dartmouth, Devon. Most of the Hussons I have come across in the UK have lived near the South Coast, in London, Chichester (Hampshire) or Exeter (Devon).
I hope this may be of some help. If you know what part of the UK your ancestors came from, there may be a Family History Society for that county who can give you more information.
